a. The radiation damage assessment shall use the total ionising dose due to charged particles and X-rays, calculated as specified in clause 7.5.2.
b. The influence of shielding in attenuating the primary particle environment and modification to its spectrum at the component location shall be analysed, including the effects of the component packaging, as specified in Clause 6.
c. The influence of secondary particles on TID shall be analysed.
NOTE The analysis can conclude that their contribution is negligible compared with the residual primary radiation components. This secondary radiation is typically electron-induced bremsstrahlung but in some circumstances secondary protons, electrons and neutrons can also have an important contribution.
d. For items in unshielded or lightly shielded locations, the energy spectrum at low energy shall be as specified in the radiation environment specification from ECSS-E-ST-10-04 clause 9.3.
